		<p>AngularJS(v1.5.8)已经成为项目们的基本框架，《玩转Angular1》系列用于记录项目中的一些好玩或者比较特别的思路。<br>本文记录在angular中使用ui-router建立嵌套路由，以及路由状态相关的过程。<br><a id="more"></a></p>
<h2 id="ui-router"><a href="#ui-router" class="headerlink" title="ui-router"></a>ui-router</h2><hr>
<h3 id="ui-router与ngRoute"><a href="#ui-router与ngRoute" class="headerlink" title="ui-router与ngRoute"></a>ui-router与ngRoute</h3><p>angular.js为我们封装好了一个路由工具ngRoute，它靠url改变去驱动视图。<br>angularUI也为我们封装了一个独立的路由模块ui-router,它靠状态state来驱动视图。</p>
<ul>
<li>两者区别<ul>
<li>UI-Router支持嵌套视图，ngRoute不支持</li>
<li>UI-Router支持多视图，ngRoute不支持</li>
<li>UI-Router是应用程序内的一个区域，ngRoute只是应用程序中的url</li>
<li>UI-Router名称可以自定义，ngRoute名称只能是url</li>
<li>UI-Router通过名称或url导航，ngRoute只能通过url导航</li>
<li>UI-Router通过状态填充某一部件，ngRoute通过指令将填充某一部件</li>
</ul>
</li>
</ul>
<h3 id="使用ui-router"><a href="#使用ui-router" class="headerlink" title="使用ui-router"></a>使用ui-router</h3><ul>
<li><p>管理状态</p>
<ul>
<li>在应用程序的整个用户界面和导航中，一个状态对应于一个页面位置</li>
<li>通过定义controller、template和view等属性，来定义指定位置的用户界面和界面行为</li>
<li>通过嵌套的方式来解决页面中的一些重复出现的部位</li>
</ul>
</li>
<li><p>嵌套状态和视图</p>
<ul>
<li>当一个状态是活动状态时，其所有的父状态都将成为活跃状态</li>
<li>状态可以相互嵌套</li>
</ul>
</li>
</ul>
<p>这里主要参考<a href="http://bubkoo.com/2014/01/02/angular/ui-router/guide/index/" target="_blank" rel="external">《学习 ui-router 系列文章》</a>，后面我们会在使用到的时候再简单讲解相关的内容。</p>
<h2 id="添加Sidebar组件"><a href="#添加Sidebar组件" class="headerlink" title="添加Sidebar组件"></a>添加Sidebar组件</h2><hr>
<p>像其他几个框架讲解一样，我们依然使用Sidebar组件进行应用程序主界面的侧边栏。<br>如图：<br><img src="https://github-imglib-1255459943.cos.ap-chengdu.myqcloud.com/1485074649%281%29.png" alt="image"></p>
<p>这里我们在维护公用组件的时候，放置在<code>app/shared/components</code>文件夹里。</p>

<p>这里我们只把关键部分进行展示，如菜单遍历、状态加载、下拉处理等等。</p>
<p>从代码中我们可以发现，模板中涉及两个在ui-router中比较关键的属性：</p>
<ul>
<li>ui-sref用于链接跳转和激活</li>
<li><p>ui-sref-active用于查看当前激活状态并设置Class</p>
</li>
<li><p>有三种方法来激活状态：</p>
<ul>
<li>调用$state.go()方法，这是一个高级的便利方法</li>
<li>点击包含ui-sref指令的链接</li>
<li>导航到与状态相关联的url</li>
</ul>
</li>
</ul>
<p>另外，我们这里使用到了$state，这个其实是从控制器传入的，属于ui-router的状态管理，下面我们会讲到。</p>

<p>在控制器中，我们主要做了以下几件事：</p>
<ul>
<li>初始化菜单数据</li>
<li>设置一级菜单点击的事件：切换下拉/跳转</li>
<li>初始化时检测并记载菜单状态</li>
</ul>
<p>这里面主要用到ui-router的$state服务，该服务主要用于状态管理。</p>
<h2 id="嵌套路由"><a href="#嵌套路由" class="headerlink" title="嵌套路由"></a>嵌套路由</h2><hr>
<p>该应用中，主要的嵌套路由使用，在登录后的home主界面。</p>
<h3 id="添加路由状态"><a href="#添加路由状态" class="headerlink" title="添加路由状态"></a>添加路由状态</h3><p>在<code>app.ts</code>文件中，我们添加路由状态处理：</p>
<figure class="highlight javascript"><table><tr><td class="gutter"><pre><div class="line">1</div><div class="line">2</div><div class="line">3</div><div class="line">4</div><div class="line">5</div><div class="line">6</div><div class="line">7</div><div class="line">8</div><div class="line">9</div><div class="line">10</div><div class="line">11</div><div class="line">12</div><div class="line">13</div><div class="line">14</div><div class="line">15</div><div class="line">16</div><div class="line">17</div><div class="line">18</div><div class="line">19</div><div class="line">20</div><div class="line">21</div><div class="line">22</div><div class="line">23</div><div class="line">24</div></pre></td><td class="code"><pre><div class="line"><span class="comment">// app.ts</span></div><div class="line"><span class="comment">// ui-router路由的参数</span></div><div class="line"><span class="keyword">const</span> routerStates = [&#123;</div><div class="line">    <span class="attr">name</span>: <span class="string">'login'</span>,</div><div class="line">    <span class="attr">url</span>: <span class="string">'/login'</span>,</div><div class="line">    <span class="attr">templateUrl</span>: <span class="string">'./modules/login/login.template.html'</span>,</div><div class="line">    <span class="attr">controller</span>: <span class="string">'LoginCtrl'</span></div><div class="line">&#125;, &#123;</div><div class="line">    <span class="attr">name</span>: <span class="string">'home'</span>,</div><div class="line">    <span class="attr">url</span>: <span class="string">'/home'</span>,</div><div class="line">    <span class="attr">templateUrl</span>: <span class="string">'./modules/home/home.template.html'</span></div><div class="line">&#125;, &#123;</div><div class="line">    <span class="attr">name</span>: <span class="string">'home.accounts'</span>,</div><div class="line">    <span class="attr">url</span>: <span class="string">'/accounts'</span>,</div><div class="line">    <span class="attr">templateUrl</span>: <span class="string">'./modules/home/account/account.template.html'</span></div><div class="line">&#125;, &#123;</div><div class="line">    <span class="attr">name</span>: <span class="string">'home.accountsadd'</span>,</div><div class="line">    <span class="attr">url</span>: <span class="string">'/accountsadd'</span>,</div><div class="line">    <span class="attr">templateUrl</span>: <span class="string">'./modules/home/account/accountAdd.template.html'</span></div><div class="line">&#125;, &#123;</div><div class="line">    <span class="attr">name</span>: <span class="string">'home.system'</span>,</div><div class="line">    <span class="attr">url</span>: <span class="string">'/system'</span>,</div><div class="line">    <span class="attr">templateUrl</span>: <span class="string">'./modules/home/system/system.template.html'</span></div><div class="line">&#125;];</div></pre></td></tr></table></figure>
<p>状态可以相互嵌套。有三个嵌套的方法：</p>
<ul>
<li>使用“点标记法”，例如：<code>.state(&#39;contacts.list&#39;, {})</code></li>
<li>使用parent属性，指定一个父状态的名称字符串，例如：<code>parent: &#39;contacts&#39;</code></li>
<li>使用parent属性，指定一个父状态对象，例如：<code>parent: contacts</code>（contacts 是一个状态对象）</li>
</ul>
<h3 id="在home-template-ts中嵌套路由视图"><a href="#在home-template-ts中嵌套路由视图" class="headerlink" title="在home.template.ts中嵌套路由视图"></a>在home.template.ts中嵌套路由视图</h3><p>子状态将把其对应的模板加载到父状态对应模板的ui-view中。</p>

<p>这样，我们就实现了路由嵌套，以及路由跳转、状态激活等功能。</p>
